[Q] CWM Recovery Problem

Hello guys,this is my first post here so don't be tough with me:)

First of all some info:
Model:Galaxy SIII GT-I9300
ROM: Android Revolution HD 15.2
Kernel: Perseus 26.1
CWM: 6.0.1.2

I recently updated normally into ARHD 15.2 and everything was normal.But after I booted up into recovery mode I noticed that those lines were on the screen:
E: Can't open /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't open /cache/recovery/last_log
E: Can't open /cache/recovery/last_log

I searched and read many threads in order to find the best and the most suitable solution but I couldn't find anything helpful.The main problem in almost every thread was that the phone had a bootloop.Fortunately, I don't have that problem.My phone boots normally.I also tried to wipe cache partition and dalvik cache in order to find any more errors but nothing appeared and my phone booted normally updating android apps.I found the thread below but I don't know if I have to do all this: http://forum.xda-developers.com/show...postcount=8311
So any help would be greatly appreciated. :)
